Abstract: An Instrumented Spherical Blast Impulse Recording Device (ISBIRD) provides for survivable test measurement of an explosive blast impulse. The ISBIRD includes a spherical housing formed of a metal having a thickness sufficient to survive the explosive blast wave from a test weapon. A test data module of the ISBIRD includes: (i) a three-axis acceleration sensor; (ii) a memory; and (iii) a controller communicatively coupled to the three-axis acceleration sensor and the memory. The controller executes a data acquisition utility to record acceleration data in three-dimensions from the three-axis acceleration sensor during exposure of the spherical housing to the explosive blast wave. An internal support structure of the ISBIRD is attached inside of the spherical housing and attached to the test data module. The internal support structure centrally locates the test data module within the spherical housing during exposure to the explosive blast wave.

Abstract: A Solid Instrumented Spherical Blast Impulse Recording Device (SISBIRD) includes a spherical housing formed of material that is resistant to an explosive blast wave from a test weapon. A test payload bore shaft is accessible through an opening in the spherical housing. A door is fastened over the opening in the spherical housing. A test data module is received in the test payload bore shaft. The test data module includes: (i) a three-axis acceleration sensor; (ii) a memory; and (iii) a controller. The controller is communicatively coupled to the three-axis acceleration sensor and the memory. The controller executes a data acquisition utility to record, in the memory, acceleration data in three-dimensions from the three-axis acceleration sensor during exposure of the spherical housing to the explosive blast wave.

Abstract: A device includes a cylindrical lattice structure inside of a cylindrical tube. The cylindrical lattice structure includes compartmentalized one or more longitudinal flowable paths formed by an additive manufacturing process. A material is introduced in a flowable state into one or more upper apertures of the one or more longitudinal flowable paths to fill the cylindrical lattice structure in a compartmentalized arrangement that provides stiffness to the device.

Abstract: A munition includes a triply periodic minimal surface (TPMS) structure attached to an inner surface of a cylindrical tube. The TPMS structure is formed by an additive manufacturing process to promote fluid permeability and to reduce pressure drop to prevent trapped air and maximize surface area contact at a structure and liquid interface. An explosive material is introduced into one or more upper apertures of the TPMS in a flowable state to fill the TPMS structure n a compartmentalized arrangement that provides stiffness to the munition.
